DUST-COLLECTING DEVICE.

Specification of Letters Patent.

Patented Mar. 1, 1921.

Application filed. February 25, 1919. Serial No. 279,117.

To (ZZZ whom it may concern Be it known that I, KENNETH BINGHAM QUINAN, a citizen of the United States of America, and residing at Somerset Vest, Cape Province, Union of South Africa, have invented certain new and useful Improvements in and Relating to Dust-Collecting Devices, of which the following is a specification.

This invention relates to apparatus of the kind in which dust-laden gases are caused to pass through channels which are of small height in relation to their width, for the purpose of facilitating the deposition of the dust from the gases.

In the construction of apparatus of this kind, within a fine or chamber through which the gases are caused to travel a plurality of trays or plates have been arranged horizontally for the purpose of splitting up the current of gas into a number of streams.

As a result of the deposition of dust upon these trays or plates, it is necessary at suitable intervals to interrupt the current of gas through such fines or chambers for the purpose of enabling the dust deposited thereon to be removed.

According to the present invention the trays in question are supported in the fines or chambers in such manner that they may be inclined sutiiciently to enable the dust settled upon them to run oft the trays. The degree of inclination will depend upon the angle of repose of the material which is caused to settle upon them..

In the construction or an apparatus in accordance with the invention, the trays may be supported along one edge on suitable members adapted to permit the trays to be rocked. while the opposite edges of the trays are connected in a suitable manner to a support which is adapted to be moved in an upward and downward direction, in order to raise the trays into a horizontal position or to cause the trays to be inclined at an angle which will enable the material deposited upon them to run ofi.

The base of the chamber in which the trays are arranged may be provided with mechanically operated means for causing the dust discharged from the trays to be conveyed from the flue or chamber.

As will be understood, a variety of methods of operating the trays in order to cause them to be raised into their horizontal position or to be inclined at a suitable angle may be employed. Conveniently, the trays may be supported at one edge by vertical rods passing through holes in the roof of the chamber and connected in any suitable manner by mechanism adapted to raise or lower these bars by mechanical means or otherwise.

An apparatus in accordance with the invention is illustrated, by way of example, in the accompanying drawings, in which Figure 1 is a cross-section of a dust-settling device.

Fig. 2 is a corresponding plan; and

Fig. 3 is a view illustrating the method of supporting the trays from one wall of theflue.

In the drawings, 1 and 1 represent the side walls, and 2 the center wall of a pair of fines or chambers, 3 and 3 representing the inlets for the gases into the chambers, and 4c and :l t ie corresponding outlets therefrom. The chambers are provided with inclined bottoms 5 and 5 and in the bases of the chambers, troughs 6 and 6 are arranged for the accommodation of a device adapted to be operated mechanically to withdraw the settled dust or to tt'acilitat-e the removal of the dust by manual labor by way of the openings 7 and 7 which will be provided with suitable doors.

Trays 8 are arranged within the lines or chambers, being hinged at 9 to members secured to the center wall, while at their opposite edges they are secured to the bars 10 supported by chains 11 secured to drums or equivalent devices arranged on the shafts 12 which are adapted to berotated in order to raise or lower the trays.

The trays are conveniently formed of relatively thin sheet metal and at their edges they may be formed as shown in Fig. 3 so that portions of such edges encircle the bar 13 which is supported on brackets 14 secured in the flue wall as shown or in any other suitable manner.

As will be understood the details of construction are matters of engineering design and therefore the detailed particulars fun.

nished are given for the purpose of indicating a suitable manner of carrying the invention into efifect and are not to be considered as limiting the scope of the invention.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a dust collector, the combination with a dust chamber having an inlet and an outlet at opposite ends, of a plurality of dust-collecting trays intermediate the said ends, means for pivotally supporting the individual trays adjacent one side wall of the chamber, and means connected with the trays to simultaneously move the trays about their pivots.

2. In a dust collector, the combination with a dust chamber having an inlet and an outlet at opposite ends, of a plurality of dust-collecting trays intermediate the said ends, means for pivotally supporting the individual trays adjacent one side wall of the chamber, means constructed and arranged to hold the trays in parallel relation and to afford a unitary motion of the trays about their pivots, and means for moving the trays about their pivots.

3. In a dust collector, the combination with a dust chamber having an inlet and an outlet at opposite ends, of a plurality of dust-collecting trays intermediate the said ends, means for pivotally supporting the individual trays adjacent one side wall ot the chamber, a member pivotally connected to each tray to afford a unitary motion of the trays about their pivots and hold the trays in parallel relation and means connected with said member for moving the trays about their pivots.

4. In a dust collector, the combination with adust chamber having an inlet and an outlet at opposite ends, of a. plurality of dust-colleeting trays intermediate the said ends, means for pivot-ally supporting the individual trays adjacent one side wall of the chamber, a member affording a pivotal support for the individual trays opposite said vfirst pivotal supporting means and holding chamber, a member affording a pivotal support for the individual trays opposite said first pivotal supporting means and holding the trays in parallel relation during pivotal motion and means for raising and lowering said member, the trays and said member being so constructed that when the trays are in horizontal position the said member contacts with the other side wall of the chamber.

6. In a dust collector, the combination with a dust chamber having an inlet and an outlet at opposite ends, 01' a plurality of dust-collecting trays intermediate the said ends, means for pivotally connecting one edge of each tray to one side wall of the chamber, a b 'acket, means for movably sup-' porting the bracket adjacent the opposite wall or the chamber and a hinge connection between each of the trays and; the said bracket.

7. In a dust collector, the combination with a dust chamber having an inlet and an outlet at opposite ends, of a plurality of dust-collecting trays intermediate the said ends, means for pivotally supporting the individual trays adjacent one side wall of the chamber, a bracket element pivotally connected to each tray along the edge opposite to said pivotal support, means for raising and lowering said bracket element, the arrangement being such that when the bracket element is in its highest position it firmly contacts with the other side wall of the chamber and the trays assume a substantially horizontal position.

, 8. In a dust collector, the combination with a dust chamber having an inlet and an outlet at opposite ends, of a plurality of dustcollecting trays intermediate the said ends, means for detachably supporting the individual trays for pivotal motion-adjacent one side wall of the chamber, a bracket element pivotally connected to each tray along the edge opposite to the said side wall and adapted to firmly contact with the other side wall when the trays are in substantially horizontal position and means for lowering the bracket.

In testimony whereof I have signed my name to this specification.

KENNETH BINGHAM QUINAN.
